DD is 5 but is very tall and looks perhaps 6 or 7. She is going through a phase this week where she tries to take her clothes off literally as soon as she leaves the school grounds. I partly think this isn't a great idea because it's too cold to be walking around without clothes, but also that she is perhaps too old to get away with being naked in public any more (as opposed to in the garden, etc, which I'm not concerned about). She isn't a toddler; as I say, she looks more like a 7 year old. I am struggling to explain this to her in an age-appropriate way. We've talked about how it's not polite, about how our bodies are private and about the "red-flag" system, and I made a very poor attempt today, whilst also wrestling my toddler, to explain that I was trying to make sure that nobody touched her body in a way that she wouldn't like. She didn't understand, and I felt upset because I thought that the explanation I'd given her was rubbish and too old for her. Am I worrying about this prematurely? At what age did you not let your DC be naked on the beach, for example, and how did you explain to them that they needed to keep their clothes on now?
